WILLIS O. MERRILL, OF BOSTON, MASSACHUSETTS.

. DISCHARGING DEVICE FOR WASTE MATERIAL.

To all whom it may concern:

Be it known that I, WiLLis C. MERRILL, of Roxbury, Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Discharging Devices forWVaste Material, of which the following isa specification.

My invention relates to a discharging device for waste material such as ashes, street sweepings and the like.

The object of my invention is the sanitary prevention of dust and disease germs arising from the dumping of city refuse, such as ashes street sweepings, and other waste material.

The dust arising from the transit of the mass from the cart to the scow or receptacle receiving the same passes through a curtain of moisture and disinfectant which forms an envelop of finely comminuted particles so that the resulting dust from the depositing of the mass is moistened and becomes heavy and drops with the mass.

In the accompanying drawings which illustrate a construction embodying my invention, Figure 1 represents a plan view of the new discharging device located over a scow. Fig. 2 is a side view of the hood showing the steam, water and disinfecting devices in section. Fig. 3 is a side view of the discharging nozzle. Fig. 4 is a side view of the discharging device showing same located over a scow. Fig. 5 is a detail view of the telescopic tube. Fig. 6 is a side view of the hood showing the counterweight and cord which is attached to the telescopic tube. a

Like letters of reference refer to like parts throughout the several views.

A represents a wharf from which the carts dump the waste material of the city and B represents the dumping block against which the carts back preparatory to dumping, and C represents a scow located in the water and into which the waste material is dumped. Secured to the dumping block B are a number of hoods D along the edge of the pier or wharf A. These hoods are cut away as shown in Fig. 6 to allow the dumping of the refuse therein and said refuse passes through said hood D into the telescopic tube E which is movable withinthe hood D by means of the cord H, fixed shaft J and loose rotatable pul ley J. One end of the cord is secured at G to the tube E and the other end has a counterweight K so that said tube can be located at any desired position over the scow. As the scowis being gradually loaded the tube is Specification of Letters Patent.

gradually raised so that the load strikes its angle of repose. The pulleys J are loosely rotatable on the shaft J but are not laterally movable. The lower end of the tube E is flaring as shown at F to allow the free discharge of the load. To the open ends of the hoods D are secured certain flexible curtains L which inclose the carts during the dumping operation.

The pipe M is connected to a suitable water supply and the pipe M to a suitable dis infectant supply respectively controlled by valves M and M. These pipes merge into a common pipe M controlled by a valve N 5 and said pipe opens into a mixing chamber M having a broad flat nozzle M as shown. The pipe M is connected to a suitable source of steam and steam passes to the pipe M controlled by the valve M into the mixing chamber M so that when the load is about to be discharged the operator manipulates the device filling the hood with a mixture of water-steam and disinfectant making a cloud of vapor throughout the hood and thereby absorbing the dust and germs and precipitating said load into the scow in a moistened state thus preventing the particles of dust and fine dirt from rising either from the discharging load or from the scow.

From the above it will be seen that the device herein described and shown not only prevents dust from ashes, street sweepings and other refuse from rising during the dumping operation, but also serves to so dispose of the mass as to keep the surrounding premises in a cleanly and sanitary condition.

Within the hood F at one side is a mixing chamber N? into which the water pipe N and the steam pipe N respectively controlled by the valves N and N enter to further moisten the discharge refuse causing it to become Wet and heavy so that it will drop into the scow in a damp mass.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new and desire to secure by Letters Patent of the United States is 1. In an apparatus of the character described, an adjustable receptacle for receiving refuse to be discharged into a scow, means for moistening said refuse to cause its discharge into said scowin a mass, and means for adjusting said receptacle with relation to the position of said scow.

2. In an apparatus of the character described, an adjustable receptacle for receiving refuse to be discharged into a scow, means for moistening said refuse to cause its discharge into said scow in a mass, means for adjusting said receptacle with relation to the position of said scow, and means for maintaining said receptacle in the position to which it is adjusted.

3. In an apparatus of the character described, a receptacle for receiving refuse to be discharged into a scow, and means for moistening said refuse to cause its deposit into said scow in a mass, said receptacle consisting of a hood in which is fitted a telescoping tube, and means for adjusting said tube Withinsaid. receptacle.

4. In an apparatus of the character described. a receptacle for receiving refuseto be discharged into a scow, means for moistening said refuse to cause its deposit into said scow in a mass, said receptacle consisting of a hood in which is fitted a telescoping tube with a flaring outlet, and means for adjusting said tube within said receptacle.

5. In an apparatus of the character described, a receptacle for receiving refuse to be discharged into a scow, means for moistening said refuse to cause its discharge into said scow in a mass, said receptacle consisting of an upper fixed portion. having an opening into which the refuse is dumped, and a movable tube adapted to fit said upper fixed portion and movable in relation thereto, and means for adjusting said movable tube.

6. In an apparatus of the character described, a receptacle for receiving the refuse to be discharged into a scow, means for moistening said refuse to cause its discharge in a mass, said receptacle being constructed with an opening to receive said refuse and with means inclosing the cart during the discharge of said refuse.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses, this fourteenth day of February A. D. 1907.
